An adhesive composition comprises: (i) at least one ethylene/alpha-olefin interpolymer, (ii) at least one tackifier; and (iii) optionally at least one additive, such as a plasticizer, wax and antioxidant. Preferably, the ethylene/alpha-olefin interpolymer has a M<SUB>w</SUB>/M<SUB>n </SUB>from about 1.7 to about 3.5, at least one melting point, T<SUB>m</SUB>, in degrees Celsius, and a density, d, in grams/cubic centimeter, wherein the numerical values of T<SUB>m </SUB>and d correspond to the relationship: T<SUB>m</SUB>>=858.91-1825.3(d)+1112.8(d)<SUP>2</SUP>. The composition has relatively higher SAFT temperature and can be used in hot melt adhesives pressure-sensitive adhesives, and thermoplastic marking paints.
